Re: Top set gets raised on the river
 

*grunch*

FLOP - perfect CR opportunity. Diamond draw should scream checkraise here...no time for slowplaying with that big pot.

TURN - looks good considering

RIVER - what hands could he have that have a seven or two hearts? Don't see any reasonable hand that has a seven, so that's not it. AhJh or something similar seems possible, but with your JJ, he'd have to have the case Jack. But would he 3-bet preflop up front with AJs? If you think so, call down. If not, reraise his a#!. Kinda seems to me he's trying to take advantage of that scare card, suggests big PP. You can't fold here for one more bet.

Cap freflop and check/raise the flop. With the fish in the hand, it's a good time for a cap. On the river, I can't see him having an overpair enough to 3-bet, and if I did three bet I'd have to fold to a cap (yuk!). Just call the river and see his AKs/AQs.
